ALEXANDER MoARTI-IUR, OF FORBES, MISSOURI.

COMBINED RAILWAY-TIE AND VIADUCT FOR WIRES.

Specification of Letters Patent.

Patented Dec. 21, 1909.

Application filed June 21, 1909. Serial No. 503,439.

To all whom it may concern:

Be it known that I, ALEXANDER MoAR- 'rnun, a citizen of the UnitedStates, residing at Forbes, in the county of Holt and State of Missouri,have invented certain new and useful Improvements in a Combined Railway-Tie and Viaduct for WVires, of which the following is a specification.

The object of my invention is to provide a means for carrying telegraphand telephone wires in proximity with the ground instead of overhead andat the same time thoroughly protecting them from injury.

The invention is especially designed to be used in connection with animproved continuous bearing railway tie for which I was granted a patentby the United States Patent Office Feb. 24, 1909, No. 93t,561.

I accomplish my object by the mechanism illustrated in the accompanyingdrawings in which Figure l is a section of a tie plate with an elevatedsection shown bolted on the same; Fig. 2 is a cross section of saidplate showing a depressed section as used below switches; Fig. 3 is alongitudinal section of both elevated and depressed section showing themanner of changing the elevation of the wires, and Fig. & is a plan viewof the main line track and turn-out switch.

Similar letters refer to similar parts in the several views.

In the drawings the tie for which I have been granted a patent ashereinbefore stated is illustrated by letter A.

B is a switch track and B is a switch.

C G are the railway rails.

D D are outside braces integral with plate A to receive the outerprotecting bases of the rails and prevent the spreading of said rails.

D D are spikes serving the dual purpose t switches and H is a sectionprovided with shoulders k h which engage with and are supported on thedownwardly bent sides of depressed section E, thus forming a lowerconduit for the passage of wires at the switches.

I I are supports for switch sectional plate H. K is a support for saidelevated plate J. The plates are preferably corrugated. Elevated plate Jis spaced about two inches at each side from the railway rails thusassisting in preventing an engine or car leaving the rails. The wires insaid conduits may be connected at stations or elsewhere in any suitableway.

\Vhat I claim and desire to secure by Letters Patent is l. A combinationrailway road bed comprising railway rails, a continuous support formedof tie-plates in juxtaposition provided with flanges to engage the outerflanges of the bases of the rails, an elevated separate plate on the topof said tie plate spaced from said rails and forming a conduit, spikesto engage the inner flanges of the rails and the flanges on saidelevated plates to hold them rigidly 011 said tie plate, centralsupports for said elevated plates and the wires carried within thespaced cham bers between the tie plates and elevated plates, and atie-plate having a depressed section for switches, a switch plate havingshoulders to engage with said tie plate at the points of depressionforming a lower conduit for wires and a support for said switch plate,substantially as shown and de scribed.

2. A combination railway road bed comprising a series of tie plates injuxtaposition serving as a carrier for wires, a plurality of elevatedplates fastened rigidly on said tie plates, a depression in said seriesof railway tie plates atswitches and a separate plate provided withshoulders adapted to engage at each end with said tie plates and spansaid depression, substantially as set forth and shown.

3. A combination railway road bed comprising a continuous support formedof a series of tie plates, a continuous elevated plate rigidly fastenedat its downwardly turned edges to said tie plates forming a carrierconduit for wires, substantially as depression forming a conduit atswitches for shown and described. wires, substantially as shown and setforth. 10
